Open new finder window same size & position via dock icon

I'm trying to see if this is possible with BTT. Specifically, opening a new finder window, preferably by clicking the finder icon in the dock with a touchpad or mouse gesture, and having the new finder window fill the same preset size & position every time. Currently my mac eventually forgets finder size & position settings after being relaunched, the mac restarting, etc.

An already open finder window can be resized via Better Snap Tools > Extras > Secondary click on a finder window button. This won't apply to a situation where there is no finder window open and I just want to click the finder icon to open it.

If this is possible I would appreciate any guidance on how I can do this. Thank you.
