Pasting multiples

Is it possible to paste an object in multiple positions, without select/move/duplicate each time? I understand linear and rotational duplicates, but this is not what I want.

I would like to paste a square in the corners of a rectangle. I create my square, draw lines corner to corner, and make it a component. This way, I can select the intersection of the lines in the center of the square component, move/duplicate, and paste on the inference point of my rectangle corner. No problem.

But is there a shortcut to pasting my square on the other three corners? That is, keep my selected square on a “clipboard”, and just click on the other corners in turn?

Thanks for a polite and helpful group of users!

Ctrl + C to copy and Ctrl + V to paste but the snap always remain in corner left bottom.

Components placer?

That plugin did the trick. Thanks a lot!
