Description
Apologies if something already exists for this but we can't seem to find a way to achieve what is needed.
Is your feature request related to a problem? Please describe.
We were trying to set up some statement forwarding rules in advance of something going live, the statements that we receive will have some extension information included that have never been passed though previously, we added this to the JSON editor but when we switch back from this it doesn't look like the filter is present on the UI. We know the format of the information that we will be receiving and the only way we can see to do it at the moment would be to get some dummy statements in there to include the filter.
Describe the solution you'd like
The ability to enter a new extensions filter, prior to the statements being received, in the JSON editor which is then reflected in the UI when switched back.
Describe alternatives you've considered
The alternative to this would be to send in some dummy statements so that the extension filter is in place before going live.
