How to add a page to an existing library template file

I hope they get a fix for this soon.

Here's the work-around I use:

I start out like I'm sending out the existing template for signature. But then on the Send page, I add the new page/ file at the end. After I press Next, I add fields to the new page/ file. Please note that I do not actually want it to send, so I make sure there are "Prefill" fields that I never fill out. I click "Save as template" before pressing "Send".  I usually use the original template name but add the date to the end to signify the date of update.

Now a new template is available.

To clean things up, I delete'/ hide the draft I created, so it is not actually sent out. I then delete/ hide the old template (or add the prefix "Old" to the title.

I need this functionality as well. I just need to replace on page in a template but now I have to do the whole thing over again.

Hello, anyone know an update on this? This is a pretty huge omission. 

That is a horrible optoin, many of the other platforms offer the ability to add, subtract or even re-arrange pages in the templete mode.  What a shame we have to go and put all those fields back just to update a policy.
