Can you create a conditional Zoho CRM field

Can you create a conditional Zoho CRM field

Hi,

I want to create a field that only lists CRM contacts associated with the CRM Account I have already chosen in my Creator app.

From the help documents I can see that you can filter a lookup field to restrict what appears in the drop down but I can't see any information that allows you to restrict the Zoho CRM "contacts" that appear so that they just show contacts attached to the Zoho CRM "account" you have already selected.

Please help.

Thanks
