Allow inserting workflow variables and building a dynamic link when inserting a hyperlink on a task form
When inserting a hyperlink e.g. in a label on a task form, you can only type in a hard coded link and cannot use the context, form fields, or workflow variables to dynamically build a link. This means you cannot easily show a link to the item the task is running on.
Please allow support to build a dynamic hyperlink like the on prem product, or allow use of the 'Related Items' field in the task form as Nintex mysteriously removes this when you customise the task form.

This is also important for created relative links to form assets, such as images. Currently, an image on a form needs to use a full URL which makes it difficult to migrate the form between different environments.
