The ability to edit 'Content by label' macro in the How- To Article blueprint

Hello,

I have a feature request for How- To Article blueprint. 

Description

The ability to edit 'Content by label' macro in the How- To Article blueprint to have certain label in the search criteria addition to the user input.

Problem

If I have a huge space that I add a How- To Article to, 'Content by label' will search from everything in that space. For example like having a label 'password'. Knowing that there are many wiki articles containing the label password would mean I would have a lot of pages show up in the Related section in 'Content by label' macro, even though they are not relevant for the topic.

Solution

A simple solution to this would be that the 'content by label' macro would have the "kb-how-to-article" label in it with the one that user inputs, so that the Content by label macro would only search from the How- To Articles instead of the whole space, and for those who would like to opt out of this just have the old method available.

Extensive solution for this would be the ability to completely edit the 'Content by Label' macro in the blueprints.
