Child plugin / plugin hacks

Hello

I see you have an update to your plugin but I am worried about updating the plugin as I have made some hacks to the core files. However I know with woo commerce it is possible to copy the template folder into the child theme and rename it ‘woocommerce’ and one can safely make edits/hacks in there as described here…

Is it possible to do some like this for download monitor?

Many thanks
