Some users create only one file with all measurements per client. But when you create a pattern you usually don't need all of them at once. And because of this searching in such big list becoming time consuming.
I propose special fetch template. Such template will contain only measurement names, but not values. It will be connected to source file and will get values from it. Valentina will see it as normal measurements file.
Of course template is not editable and all changes will go to source file.
Idea came from the forum thread.
