Not adding people / removing them as assignees if they are on holiday

Hi,

I just found your plugin and it makes wonders for me !

I was just seeing that the planning is taken into account for adding a technician, so if the person is away an error pops up, which is great.

I was just wondering if there was an option not to add the person or remove them out of the box, or if it needs some coding.

Best regards,
