You missunderstood.
I like to know that to understand the goal
1. For better help
2. For me, to learn new thing(rare, but sometime i do)
Besides, it's just nice to answer the question, because I (we) donate our time to you and your problem.
In the whole thread you talk and write about OPEN a DWT, what is unusual after the dwt is set up well.
Sometimes you need to edit also a dwt, but so often that you like to have a menu for it??
I just like to know your situation and why you need this process often.
Or do you need this button for 2 use in a year?
Usual would be to have a button to create a new file based on templateX
for the taskX, templateY for the taskY...aso.
That is what "normal users" need,
but then we talk about command NEW and not about OPEN.
I like to help you to solve your issue (i have expierence with that HELP popup too).
But for this is good to make sure that i understand you and that your try is the right one.
So i waited for your answer/explanation.
If you have the same trouble like me in the past, it isn't a short answer to solve it,
we have to search for it with some tests.
Later more, if you want.
