Best practice for adding members manually so they can renew.

I have a member organization. It has an annual subscription from the date a member joins. I’ve made some temporary subscriptions for each number of months remaining on a subscription for current members – i.e., if they renew in two months, the subscription is Temp2 (expires in 2 months). These “temp” memberships are set to private. Manually adding members makes the gateway “admin”.

My question is: Do I need to change the “gateway” to “paypal” for members to have a paypal renew button for the regular “professional” subscription (1 year, public)?
