tag update with several tags

[artwo]

Hello,

I'm trying to create the following rule in tagupdate file:
@RATING=5
&CUSTOM1=2017
+CUSTOM1=Best of the moment

CUSTOM1 is related to last added albums. Unfortunately, this rule doesn't work. Is this possible to create rules with several tags involved?
If not, it would be great to create "dynamic playlist".

One remak also. In the file, I have a rule like that:
@CUSTOM1=2017
+CUSTOM1=Recent
@CUSTOM1=2016
+CUSTOM1=Recent

It would be wonderful if a parameter could refer to the current year
