Variable inside variable

[irmscher]

{-Variable.Sentence{-Variable.Count-}-}

Something like that, but I know it's not possible, may be there's some way around?

I just don't want to replicate one and the same action multiple times.

in code:
return project.Variables[project.Variables["b"].Value+project.Variables["a"].Value].Value;
