Device list filtering in experience view

I would like to have a list of devices on an experience dashboard page along with clickable links to another dashboard experience page with detail gauges. I’m wondering he easiest way to filter the list given an array of devices obtained from the GetDevices node and that the list should be filtered to only include devices belonging to a tag identifying the group of the current experience user? From what I can see the filter box in the Device List block is not templateable.

In the absence of being able to template in the filter box, I’ve tried passing down a pageData object that contains the value of my desired tag but it doesn’t seem possible to use a context variable in a device tag query like this: Customer={{ctx.customerTag-0}}. Seems the idea of making this possible was was discussed in the past in this post.

Thanks
