Today, if you attempt to use the addHiddenFields form method with Marketo's JavaScript Forms API when attempting to write into a Program Member field, the platform requires that you have at least one program member field populated on the form itself inside Marketo. For example, if I have PMCF fields 1-10, you must have at least "PMCF Field 1" hidden on the form directly for PMCF Fields 1-10 to record.
This requirement is not in place for standard Marketo fields; could we please get the ability to directly write into PMCF fields without this additional step? This becomes problematic when needing to adjust forms at scale.
