Settings different default paper sizes with different printers on Ventura

Shocking that we're up MacOS 13.5.2 and Apple still doesn't realize that users could have MULTIPLE printers connected, each needing different print setting defaults...

Anyway, as others have said on other long-closed posts: I'm running Ventura and am connected to three distinctively different printers, each in need of different default print settings: Epson 11x19 Surecolor, a Brother 8.5 x 11 laser printer, and a 4x6 thermal label printer. I need to toggle between all VERY often. And in the case of the laser and label printer, for each product shipment I create.

There seems NO WAY to set a default paper size for each printer. Printers & Scanners dialog in System Settings does nothing. You can only set an overall default printer and paper size. Though you see a list of printers, when editing each, "default paper size" is not an available option. (first screenshot) So this is not the solution.

When going to any application's print dialog box, you still need to select Page Setup and Printer buttons to select the correct printer and paper size. You would think once you set a custom paper size for a printer, it would "stick", but nope. It will immediately default back to the default paper size you've selected in Settings. This is also not the solution.

I know in the grand scheme of things, this isn't a big deal. It would just be such a UI improvement. And maybe it's something simple that we're all missing?

BTW: while we're at it, does anyone know how to remove the long list of paper sizes associated with a printer driver? (see the last screenshot above) Back in the old days, you used to be able to edit/delete those within one of the print driver files? And to clarify, NOT the "Custom Papers".

Thanks for anyone's help.
