TC11 - NX10 Variants management

Hi Experts,

do you know if is ti possible change variant option once you have the assembly loaded in NX managed?

I mean, question is about not to have to close and open the assembly that containts variants to change

the variant .

One more question....is It possible open and load the variant from NX and not to have to choose the option from Structure manager and then from TC an NX?

All considerations have to be managed from TC11.2.2.1 and NX10.0.3.5

Thanks in advanced for your collaboration and help!!!
