Show specific assets in Content Browser

When I get a list of assets(e.g, some blueprints has same parent), and I want to show them in the content browser.
For now, I use the following code to show assets selected:


However, if the assets are in different folders, the other assets in these folders will show in the content browser(as you see, there could be lots of assets).

My problem is, is there a way to show specific assets in content browser and no other assets?
