How to create a Performance document approval rule based on the document name

Content (required):

Hi,

we would like to create two different performance documents (based on different performance templates). Each document has to include an approval task. Our aim is to differentiate the approval rule for these two different documents. In other words we would like that the first performance document follows a certain approval rule, while the second document follows an approval rule different from the first one (namely we would like two different approval rules whose assignment criterion is the name of the performance document).

Hoping someone has some suggestions.
