Pivot points circle diameter

Hi,
I set the pivot points for every parts I need, and everything move well.
However, some drawing elements has very large rotation circle sizes, when some of them has small diameters. Is there any way to change the sizes of them but doesn’t affect the positions of drawings?

The Rotational Pivot is always created at the centre of the Drawing-Grid…
Draw your object in the centre of the Drawing-Grid… Apply your Rational-Pivot…
When you now move the object with the Select-Tool (6) the Pivot will stay
with that object and keep it relative size.

As far as I know, there is no way to move it in any other way…
