Adding Time Units to a process ticket

[retro2707]

Hi,

Maybe im missing something here but I want agents to be able to put how much time they have spent on each step of a process ticket. On normal note and other updates you have the Time units option as shown below.

2015-05-11 09_41_21-0110678 - Note - Ticket - OTRS ITSM 3.3.12.png

I cant seem to get this showing for a process ticket when you select an action dialog. The option does not appear as a selection item from what I can see.

Is this possible?

Thanks.

Brendan
