At present, the Filter does not provide a means of specifically targeting barlines. Users who wish to select or deselect only barlines must do so manually, which is inefficient.
Feature Request
Introduce an option in the Filter that enables users to select or deselect barlines only. This would streamline workflows when working with notation or score editing, particularly in projects where barline manipulation is frequent.
Benefits
• Quicker editing of barlines without affecting other elements
• More precise control in score and notation workflows
• Consistency with other filter options (notes, dynamics, articulations, etc.)
Barlines are automatically generated by Time Signatures.
May I ask what kind of changes you need to do? Can you post an example and describe what you are trying to do with the barlines?

It seems that you are using a 1/4 meter to have everything evenly spaced? I believe you actually could avoid using a meter at all and use note spacing settings to space evenly instead. Then you would save a lot of time. But maybe you have other reasons for this way to do it.
On the other hand, if you set your document to use dashed barlines as default, and then in engraving options do this:
