Blocks random seed rotation around basepoint

Blocks are great and help a great deal with complex scenes where you have to make changes on the fly… But when you’ve populated your scene with instances you still have to make changes to the orientation of each instance.

I have 15 blocks with 500 instances and I want to rotate each instance by a random number of degrees around the basepoint - I have to do it manually.

Would it be possible to add a translation/randomise seed rotation option to the block manager similar to @pascal’s sprinkler but just for rotation around the basepoint of the block?

Cheers
