FR: shield augmentations to get the same treatment as shield attachments

[ThingsCouldGetDicey]

I had an issue where my players wanted to add a sheild augmentation and wanted to run it to provide potency boosts to their new traits they are adding via the augmentation. as from here https://2e.aonprd.com/Equipment.aspx?ID=1430

currently the only work around is adding a shield boss and doing the runes on the sheild boss. but it would be nice if they work the same way attachments work.
