Hello,
Thanks for contacting us.
Try to use our brands functionality for this. Rename Brand to Collection, using translation files (Install Loco translate plugin https://xstore.helpscoutdocs.com/article/30-base-theme-translation , create English translation, change desired strings of XStore theme/Core plugin and disable the Loco translate.)
Via Theme Options > WooCommerce (Shop) > Shop elements > Brands > Choose The Location For Brands > In product meta – http://prntscr.com/pcdly0
