This is not possible with the latest release. However, you can achieve a similar result by enabling the parameter feed setting "Auto-select all" and linking the feed with indices from the URL feed. Then you can provide an index filter in the URL which will be used when fetching the indices. In your case the url could look like: [dma]/dashboard/#/db/[dashboard].asmx?indices=*inlet*/*inlet*.

This has a few downsides:

• the filter is bound to the url, and not to a dashboard. So you cannot configure it to be default behavior for all users.
• Using an index filter on the feed is actually making (mis)use of another feature, which will cause the indices to be hidden in the feed. That's why the "Auto-select all" setting is also required for this to work.

To have this work as a configuration of the dashboard, we'll need 2 new features:

• Being able to create custom index/filters, than can then be used as filter. (which is a very useful feature for many use cases)
• Have a way to still show the indices when a filter is applied in the parameter feed.

I hope this contains the info you were looking for.
