Can HTML template import be made sticky?

I'm publishing to HTML5 with Frame 2015, but it seems the html template has to be reimported every time. This is what I see:

1. Modify a custom template.html
2. Open settings.
3. Import custom template.
4. Save and close custom .sts settings file.
5. Publish.

Now I will see my changes. For example, if I changed the footer.

However, if I change the footer again and save the html template, I don't see those changes in the output unless I redo steps 2-5.

Is this the correct behavior? If so, any way around having to repeat the steps?

TIA
