Assuming you use a composite column (column built from other columns) that behaves like tags, they are clickable without using the PI. Are you seeing something different?

And just for fun I made a composite column that lets you switch VLs by clicking the links in book details. The GPM template is:

program:
	res = '';
	for vl in virtual_libraries():
		if res then res = res & '<br>' fi;
		res = res & '<a href="calibre://search/_?encoded_virtual_library=' & to_hex(vl) & '">' & vl & '</a>'
	rof;
	res

The column definition is:


What you see is:


And for more fun, here is the template using python template mode (PTM), which will be much faster than the GPM template above:

python:
def evaluate(book, ctx):
	db = ctx.db.new_api
	return ('<br>'.join(
		[f'<a href="calibre://search/_?encoded_virtual_library={vl.encode().hex()}">{vl}</a>' 
		 for vl in db.virtual_libraries_for_books((book.id,))[book.id]
		]))

EDIT: corrections to the column setup and the python template
