Part L: Change a template without losing data

[RossThompson87]

Hi,

Typically for Part L models, you first assign an NCM template then enter details for the lighting, systems ventilation etc. by overiding the defaults.

If you then decided to change the template you have to start again.

Could this be improved so the template could be changed preserving all the previous overides?

If for some reason it doesn't work e.g. replacement template doesn't have display lighting this could just be flagged with an error warning.
