Default value for a multivalue field

I have a requirement to automatically populate a multivalue field with a default value in a version. It must be automatically populated when user expand the multivalue field.
Is there a way to do this?
I initially tried using the AUT NEW CONTENT, but it just populate the default value in the first multi-value, but doesn't dsplay when I expand the multi-value field. Definition in the version is the following:

Autom Field No.1 --> IN.FREQ-1
Aut New Content.1 --> Monthly

Thanks in advance

Hi
you can try the VALIDATION.RTN but I afraid it only triggers when user inputs something, not right after field expansion.

Hi VK, thanks for your help. Unfortunatelly it didn’t work.
Default value is still not populated after expanding the multivalue field.

Any other idea?

Hi
I afraid there's no such functionality in T24 - at least to my knowledge.

Maybe some javascript tricks but I never tried that.
