import into existing form

Is it possible to export a form on one installation, then import it into another, overwriting an existing form?

I'm doing some local development, which I then need to put on staging, and probably transfer across to other local dev environments too (e.g. home desktop). I'm working on the same form, creating custom code with actions and filters that hook using form IDs.

Currently, you can export an individual form, but when you import on another installation, you don't get the option of overwriting an existing form. Whether you just import, or you delete the current form and then import, you end up with a new ID, and all the code breaks.

I can appreciate that a facility to overwrite an existing form with new fields would generally not be advised because you might lose entry data. However, during development this would be very useful. Actually, at the moment, it's essential for me unless I get into a lot of very time-consuming synching of form structure and field settings between different installations.

Well, deleting a form can create severe problems. But it's a very useful if not essential piece of functionality, so there's a confirmation pop-up. Why not just use this?

For now it looks like I'll have to use something like the CSS class to uniquely identify the form in different environments.

It's a little shocking that an otherwise well-thought-out, paid-for plugin is lacking anything to definitively deal with different installations on different servers. I'll put in a feature request.
