Yes, you can. On a large scale, it's called "artificial selection" and it's what breeders do all the time. They engage in selecting which allele expressions get to reproduce for the next generation. And in the case of insemination, we have the ability to select which embryos get to be allowed to progress to maturity.
In fact, selective pressures can be so strong as to direct specific mutations within the genome. At the most primitive level, we must recognize that the genome itself is in an environment and thus, the chemical environment in which it finds itself will affect how it mutates. For example, 5-uracil causes specific kinds of point mutations. And we know that mutations happen in certain areas of the genome more than in others. Again, the physical environment in which the chromosome finds itself has an effect on how it mutates.

ny attempt to insert a "plan" into evolution is bound to fail, because the plan gets degraded, randomly.
That assumes that you allow non-controlled reproduction. If all reproduction is controlled, then you can most definitely "plan" your evolutionary path.
Personally, I don't see any evidence of any such omnipresent tinkering. It is along the lines of those who claim that evolution is "mathematically impossible" not quite realizing that this necessarily means that god specifically, consciously, and deliberately came down and made sure that every single mating pair was specifically planned, deliberately caused the specific ovum and sperm to join, caused the two to mate at that specific time, in fact controlled the entire thing.
This, of course, leads us to the question that never gets answered:
Is there anything that happens on its own or is god required for everything?

The notion of evolution following some kind of specified plan is just a non-starter.
Yes, but not because the concept is untenable but rather because it is impractical and unevidenced.

Thank you for your submission to
Science. Your paper was reviewed by a jury of seventh graders so that they could look for balance and to allow them to make up their own minds. We are sorry to say that they found your paper "bogus," specifically describing the section on the laboratory work "boring." We regret that we will be unable to publish your work at this time.
Minds are like parachutes. Just because you've lost yours doesn't mean you can use mine.
