Merge one size variant into two tilter groups

Topic summary

Issue: A store has size variants such as UK10, UK11, and combined UK10-11. They want the UK10-11 variant to appear under both the UK10 and UK11 storefront filters.

Constraint: Shopify’s Search & Discovery app (used for storefront filters/search) only allows merging a variant into a single filter group, preventing assignment of one variant to multiple groups.

Request: A method or workaround to have UK10-11 included in both the UK10 and UK11 filter groups (i.e., multi-group mapping for a single variant).

Latest update: Another participant asked if a solution was found, but no answer or workaround was shared.

Status: Unresolved. No confirmed solution, decision, or action items provided. Key question remains whether Search & Discovery or any alternative approach supports assigning one variant to multiple filter groups.

We have inventory with complex size variants. For example, some product variants are size UK10, some are UK11 and others are UK10-11. I need the UK10-11 to sit in both the UK10 and UK11 filters. However, Search and Discovery only allows you to merge a variant into one group.

Is it possible to merge UK10-11 into both the UK10 and UK11 filter groups?

Hi, have you found any solutions as to how to solve this?

Thanks
