# Exclude several features at once

Asked by Sabrina on 2020-01-16

Dear OF Team

I use openforis for a forest inventory.  Features of plots and trees are recorded.
The inventory is done regularly. Therefore there are already default data for the trees. 
One attribute in the tree table is "sample tree existing". If "yes", the sampling can continue normally. If "no" a reason must be given. The following features cannot logically be determined. 
Is there a command with which all other tree attributes no longer have to be filled in? Or do I have to do this via the "Relevant" field for each attribute individually?

Thanks for your Support

Dear Sabrina,  
Unfortunately this is not possible at the moment; you have to specify the `Relevant when` expression in every attribute, unless you move all your attributes inside a single entity (group of attributes) and specify the `Relevant when` expression only in that entity.  
Many thanks,
