Quicklink to open a file with a particular app?

Is there a way to make a quick link or script to search for a file and then open that file with a particular app?

Use case: I know there is an extension to use AppCleaner or PearCleaner to uninstall an app, but I'd prefer to use TrashMe 3, and the extension will not let me select it as the cleaner app.

Thanks in advance!
