renameAnnos doesn't seem to work on token annotations?

[amir-zeldes]

Is the property pepper.after.renameAnnos supposed to work on token annotations? It doesn't seem to work for me and it's important for example if you want to distinguish POS annotations coming from two different formats that automatically generate an annotation called 'pos' (e.g. conll and TT).

For example in a conversion from CoNLL I tried to use the following, which doesn't seem to do anything:

<property key="pepper.after.renameAnnos">pos:=conll_pos</property>

If I'm doing something wrong please let me know, otherwise having this work for token annotations too would be great!
