Can I make istikhara about two things?

For example if I want to be a doctor there is a summer research program I could do that would help me in my medical school application and I have already made istikhara about that.

But I have also thought about nursing as a field and there is a job I want to apply for in case I choose to do nursing instead and if I do the research program I can't do the job for the nursing field and if I do the job I can't do the research program so they are both conflicting with eachother.

Can I still make it about the nursing job too?

What if applied for both the research program and the job and I get both then what do I do?
