Invited by a PI to join their lab but I want to do rotations...what to do?

[windance]

I have been invited early by a PI to join their lab.  I want to wait to hear from all of my schools.  Once I"ve been invited by one PI at a school is it still possible to be invited by another PI that was on my list?

Probably needs a bit more context... does the program normally do rotations? Is this form of "early" admissions a part of the program's setup? Usually PIs reach out to tell you that they'd love to have you join, but that just means they want you to rotate and then hopefully stay. Most bio programs have a required number of rotations anyway.
