Transfers - retain existing registrant possible?

[Bob's Lists]

I have a slight problem with bulk transfers...

I am tech, admin and billing contact for a whole bunch of domains. I
would like them all in my OpenSRS control, in one profile, but I *don't*
want them all to change to 'me' as registrant - they're currently all
different registrants...

In other words, I want to bulk transfer a bunch of domains to my (one)
profile keeping myself as tech/admin/billing contact but leaving the
existing 'registrant' details intact.

I'm not sure how or if this is possible perhaps someone can enlighten
me...

Regards

Bob
