Add option to change service on change queue action

[MatjazBF]

Hi I would like to add an option to select a service when an agent clicks on Queue action to change a queue of a ticket.
...index.pl?Action=AgentTicketMove...

I'm able to add dynamicFields that I have created but I don't know how to add a service.
I have tried to add DynamicField "Service" and "AgentTicketFreeText###Service" but with no success.

Thanks and best regards, MatjazBF
