Any previous Maya users here? Need help with pivot points

Ok so I made this simple model made up of spheres and I’m parenting them to each other to resemble limbs. I figured out how to set the pivot points for each object. However if I rotate, lets say the thumb, it would rotate towards the x axis. In Maya you could hit the insert key and go into pivot point mode and rotate the pivot around. Is there a way to do this in Blender? And would I be able to mirror the objects to the other side of the x axis with the pivot points set? Thank you in advance.

I am not sure how Maya acts, but in Blender you can pivot around the 3d Cursor by hitting “.” and then restore the default pivot with “Ctrl+,”

Also, keep in mind that you can precisely place the cursor by making a selection (in Edit Mode or Object Mode) and doing “Shift+s,c”.
