virtual link, trunk links and restricting allowed vlans over trunk

Hello I am looking ot limit the vlans allowed over my trunk links and I see that over a 'virtual link' I have vlans being sent over the trunk and I want to only allow certain ones.

usually I would accomplish by the following (some data omitted for brevity) interface port channel x ... ... switchport trunk allowed vlan x, xx, xx, xxx, xxx, xxx ... however, on an interface configured as a virtual link that command is not even available.

interface port channel x ... ... switch virtual link 1 ...

am I missing something? is there another way to do this? (for example within the virtual domain creation?)
