Would it be possible to add a simple way to mark individual recipes in a production line as completed or built?

For example, after I finish building a part of the factory, I could click a checkbox (or use a modifier + click) on that recipe. The recipe row would then be grayed out or otherwise visually marked as completed.

This would only be a visual/organizational feature. It should not remove the recipe from calculations or change any production values.

For example:

□ Advanced circuit
□ Processing unit
✓ Iron gear wheel — grayed out
✓ Electronic circuit — grayed out

For larger production lines, I often use Helmod as a guide while actually building the factory. Being able to mark recipes that I have already built would make it much easier to see what still needs to be constructed.

If possible, the completed state could be saved with the production line so that it remains after closing and reopening Helmod.
