How to save my custom module positions from overwriting by template updates?

Hi,

I've created some custom module positions in the T3 BS3 blank template. It works fine, however I'm afraid that I'll run into trouble when updating the template. I changed these files as listed below; also I've created a local theme of the template'. Could I store my changed files in the /local folder to prevent them from being overwritten? I called my local theme: 'extended'.

Files that are changed:

templates/t3_bs3_blank/tpls/blocks/mainbody.php
templates/t3_bs3_blank/tpls/blocks/mainbody/ -> all files in this folder


Also I've created a few new files in order to add positions of the 'spotlight' type:
templates/t3_bs3_blank/tpls/blocks/spotlight-3.php
...
templates/t3_bs3_blank/tpls/blocks/spotlight-7.php

I supposee that the latter files are safe as there are no original files with these names. Still I'd like to store them in my /local folder to keep my files well-organized.

Is this possible?


Kind regards, Frits
