List Custom Parameters of defined page

Hi everyone,
I am trying to create a list consisting only of the custom parameters of a defined page of an operator.
baseOp.customPars lists all custom parameters. The list this command creates does not hold any page information.
Do I have to use TDJSON for this?

Thanks in advance,
Hendrik

Try the page class
https://docs.derivative.ca/Page_Class

And TDFunctions has
getCustomPage(comp, name)
