Currently, only a limited set of custom field types are enabled as filters, such as multiple and single options. We use custom fields to feed marketing campaign data to deals. These are automatically filled when deals are created. Examples are Google Ads campaign IDs. Setting these fields up as single options with a predefined set can cause errors since every new value generated in 3rd party apps (new google ads campaign ID) would have to be set up in Pipedrive as a value in the single options custom field. Not a good process.

Therefore we request to add text fields for filters. The same goes for monetary and date fields.
