A metal plate with studs welded or tapped and the plate marked with alignment once set up.
You can carry out an aluminium pier and bolt it down in the correct orientation each time. Pretty much what you do with the top of a pier. Aluminium , thin large diameter would make it light and easy to move.
The metal plate can be bolted to concrete base with screw anchors which are easily removed and replaced. Or bolted to light weight screw pile or hammered pile type footings which are also removable.
The draw back is the cost. So just leave your tripod out there on three marked pavers to try it out.
