Making Card Start Date field not required

Hello,

The field “Card Start Date / Issue Number” is mandatory and we would like to make it optional or remove all together.

How can this be achieve?

I looked up several topics on your, such as http://www.s2member.com/forums/topic/making-card-start-date-field-not-required/, but the answer never gets revealed.

Thank you for your help, awaiting your reply.
