Update Simple list in a Request Offering automatically

Question

Hi,
I want to update a simple list (add a value) automatically. I have 2 options:

1- Doing it using Powershell: I tried to find out how to get values of the list, the only place I could find it is:
$ParentClass = Get-SCSMClass System.RequestOffering$
$RequestOffering1 = Get-SCSMObject -Class $ParentClass -Filter "ID -eq 1|ServiceManager.ServiceRequest.Configuration|1.0.0.0|Offering0a4b6622954d4d63a7a5e74fa430955c|3|RequestOffering"
$RequestOffering1.PresentationMappingTemplate

I'm not even sure if I'm pointing to the right direction

2- Doing it using Orchestrator: Haven't found clues in internet about it.

Can you please direct me to do it ? Either ways are good for me.

Answer 1

I think adding a value to a simple list in a Request Offering automatically isn't that easy if even possbile.

Can you share some more details about the use case please? Maybe it's possible to find an alternative for your requirement.

Kind regards
