Punchout from eBS iProc directly to item page from supplier

Currently we are using Endeca to load punchout items from OSN directly to ICX_CAT_PUNCHOUT_ITEMS. These items are made available through Endeca so you can search on them and click on the link to go the supplier site.

Unfortunately this only works for cXML by the way, in the XML message the item is not passed to the supplier, so you always get to the main page.

But besides that .. I like to know if it's also possible to

a) Either load the items through OSN and search on them in standard iProcurement and do the punch out?
