Is there a way to move an objects/planes origin?

Hello Everyone,
I am rather new to rhino but have used other 3D programs in the past.
Is there any way to move the origin of an object or plane to a specific location, like one of the corners, and have it remain there until moved again? I know you can select a rotation point if you use the command but I would like the origin to remain there so I could quickly experiment using gumball.
Thank you for reading.

A block has its own origin and you can define where it is

for single objects you can position your gumball anywhere you like, just use relocate gumball. every time you then click on the object the gumball will show at the position you left it. this does not work for groups of objects.
