Membership feature request

our site has a set due date for membership, June 30th of each year. Our members can pay for more multiple years but the expiration date is always on June 30th.

Would like to see the following options in the Membership plugin

1) Set a default expiration day and month. When new memberships are added the default expiration date will be applied.
2) The ability to manually modify expiration dates in the WP admin. Instead of having to make the changes in mysql.

thank you!
