Renew Membership Before Expiration

I want members to have the ability to renew their membership before it expires. I don't see a "Renew" button unless the membership has already expired. A lot of our members will be paying manually with a check and they need to be able to re-up at any time. Others use recurring payments via PayPal and they also need to be able to renew.

Can we direct them to a "Renew your membership" page?
Do we need to change all of these to "Finite" access? This would then remove the auto-renew capabilities, which we don't really want to do.
