Stencils and guidelines

I would like to print some business cards and organ donor cards, for example. I don’t want to have to align them every time and position them in the suite using the preview function. I would like to laser cut a template and insert the aluminum card or organ donor card into it.
Then I would like to load my project and have a frame where I could enter and move the business card data and then say that the stuff should start exactly at coordinates 30/30 or so, because that’s where the template is located.
How do I do that? When I draw a frame in the project, I have to tell it what it is, but it shouldn’t actually laser the frame. It’s just for my own orientation. To do this, the frame and text are always at the top left of the platform. I can move the group, and it also displays the coordinates, but without decimal places. The preview image helps, but it’s never as accurate as if I could just tell it to print the project at position 30/30.
I would also like to be able to change a QR code I have created without having to delete it and reposition it, etc.

So, my specific request for the suite is:
-Declare objects as “guide line, do not print/laser”
-Position using text fields in the preview as on the first page.
-Make QR codes editable

Or am I just too blind to find these functions?
