[dukeofharen]

Feature Request

Describe the Feature Request

It is possible to add variable handling parsers to your responses for e.g. inserting a date & time, UUID etc. Right now, you can insert these handlers in the UI, because each handler has an example defined. Sometimes, it would be nice to be able to select more than 1 example (e.g. for issue #72).

Describe Preferred Solution

Each handler should be able to provide a list of examples. The examples can be selected through the UI.
