error while using variable for selfhost runs-on

[Arunkumar Gaddam]

Hello team,

I would like to store label as variable in runs-on step

ex:

- step: 

           name: use selfhost

           runs-on:

               - self.hosted

               - linux

               - ${{label}}

Since we repeat the step in multiple repos, we would like to store label information in repository variables

does pipeline currently support this ?

if not how can we make it work ?
