No.
All attributes that you mod get
replaced (not mixed, merged or anyhow else combined):
- if a value was 24 and you change it to 42... only 42 remains
- if a value was [1,2,3,4] and you change it to [5,6,7]... only [5,6,7] remains (not [1,2,3,4,5,6,7])
...everything else worked like that, but for some reason it didn't.
Actually, quite the opposite, nothing works like that (with maybe 1 or 2 exceptions which I won't even mention to not confuse you).
