Feature Request: Bulk apply GemPages template to a specific collection only

Hi GemPages team,

I'm a Shopify merchant who actively uses GemPages Builder and really enjoys it!

Currently, when applying a product template, the only available options seem to be:

• Applying it manually to individual products one by one, or

• Applying it to the entire store at once.

Since most sellers organize their products by collections, it would be extremely helpful to have the ability to bulk-apply a template to all products within a specific collection only.

This feature would make workflow much faster and more efficient for many of us. I'd greatly appreciate it if you could consider adding this option in a future update!
