Turn a spreadsheet into one link
A haul share page is the sheet you already keep, opened as a page people can browse. Put agent links into the catalog, then put that one link in your bio.
The spreadsheet stays the source
Import the sheet. Product names, photos, and prices come in with the rows. You curate what stays public. When the list changes, the haul share page is the link people already have.
What the haul share page is
One public link. Your audience scrolls the catalog instead of downloading a file or asking which row to buy. That link is what you paste into a link in bio.
Put agent links into the catalog
Buying agents stay attached to the catalog. Add the agent links you want, and a promo code on each one. The haul share page stays yours. Checkout stays with the agent. Buyers pick a product on your page, then continue through the agent you chose.
