Odd question regarding token size and grids.

Howdy,  My friends and I have recently started a Black Crusade 40k game, and when you play as a Space Marine your size is set to one up from normal. So, a 4 square token. Is there any way I can adjust the size to four squares, but consistently keep the center of the token on one of those squares, rather in the corner of 4 without using ctrl drags. Thanks for taking a glance.

I would suggest making a second image that is 3x3 with the image taking up a 2x2 space and transparency around it to fill out the rest of the space, then use that as a rollable token with the original 1x1 sized token. When it increases in size it’ll stay centered.
