Will we ever be able to mount up with our companion out?

Would like to be able to mount my Coeurl while my Companion is out. Having to run from fate to fate on foot to conserve greens is bit of a inconvenience.

<.< "But the greens are butt cheap! Just buy stacks of the stuff!" Well, 3k something for a stack is a bit pricey for me since i'm not great at making money, so i ain't got hundreds of thousands of gil o.o;

Thanks!
