[Feature Request] Allow custom fields to appear as columns in Requestable Assets end-user view

[lwagna]

Current problem:
Almost duplicate of issue #8276 where end-users cannot see custom fields or even any of the other existing fields for requestable asset models when trying to request asset models. The only things visible for requestable models are a picture, the model name, number available (which doesn't seem to work as it shows 0 even when I have more than 1 marked as ready to deploy, maybe that's just me I'm not sure). We cannot show even a purchase price unless it's part of the model's name which leaves users not as well informed as they could be when requesting items. Picture attached for reference

Possible Solution:
If different columns could be selected similar to the column chooser for the all assets table or if a set of default columns could be changed in the end-user view of requestable asset models, they would be able to be more informed when requesting items as they could see any information we might need to show such as an approximate cost as cost.

just to note on top of this and perhaps it should be its own request, although the quantity of the requested items appears in the email when a request is received, inside the requested assets view it does not show the quantity which would make the asset requesting feature much more usable
