Need to Merge Accounts

Please allow two separate WorshipTools accounts to be merged.

I have my own account for music, and often the ministries I'm hired to sing at have their own separate account in which they have created slides for the talks & worship services. They don't want to ex out of their Presenter account and re-log in every time I sing. We need the client's Presenter account to be temporarily merged with mine (for the duration of the event) so that what both of us have prepared can be used at the same event. Please and thank you!
