Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.
In the final dossier you would be able to select multiple elements in a grid and the URL below will be updated with elements you've selected.

In order to do that you would have to create two metrics:
METRIC 1: AggCompNames with formula:
ConcatAgg(CompanyName){~+}

METRIC 2: Multi Link with formula:
Concat("<a href='https://www.google.com/search?q=", AggCompNames, "' target='_blank'>Search for: ", AggCompNames, "</a>")
This is basically a regular URL that you need to split into pieces and replace 'xxx' with the first metric you've created.
<a href='https://www.google.com/search?q=xxx' target='_blank'>Search for: xxx</a>
