dynamic field: change key pair - howto ?

[massimobianchi]

Hi all,
I am running helpdesk 3.1.13 / itsm 3.1.6 on Linux / centos.

I setup a series of dynamic field with key:values pairs like
1:buildingA
2:buildingB

100:buildingAZZ

I have to insert those values into event generated messages.

In otrs 3.2.x i know that's possible using dynamicfiled_name_value, but this is not available into 3.1.x.

I would change the key:value to be the same, but this has adverse effect over the values already inserted.

Is there any clever way to to it ?

Thanks and regards,
Massimo
