automatic synchronisation of subject selection?

[Carlos-Versieren]

Hello, 

When i select multiple photo's in the latest version of lightroom, and i then make a "select subject" mask, the mask gets automaticcally copied over to the other selected images.

That's great. BUT the mask is not made correct and displays a warning sign. When i click the warning it says that the mask has to be recalculated. 

The problem now is that i don't find any possibility to "recalculte". 

Does anyone know how to solve this, or is it just impossible to automate that 'select subject' command?

When you select the mask, you can find the "rebuild" butt in the option below the toolbar.

thank you very much, i missed that button...   

so i can automate the process in a way but need to rebuild the mask on every image...

still it helps...  

thanks
