Supporter Plugin - Supporting up to (say) XX blogs, possible?

Hi,

With the Supporter plugin, can I offer supporter privileges to the member for up to say 5 of his/her blogs instead of just one?

For example, once the member upgraded to Supporter, he/she can add up to 5 blogs in his account/dashboard with all 5 enjoying supporter privileges. Either he/she cannot add the 6th blog or the 6th blog onwards will not have the supporter privileges anymore.

Can this be done?
