Fasspass+selection on the days not staying at resort

[marathon]

If I make a resort reservation for 4days, and link my 3 day tickets purchased ahead separately, can I make fast pass+ selection ahead of time for the days before my resort stay(stay offsite before my resort stay)? I will upgrade to AP later at the park. Thanks in advance!

Try it and see what happens.

If it works... great!

If not, you will be able to make FP+ IN the park(s) on the day(s) that you are there.
