Merge only null values in Power Query columns

Hello guys.

 

I'm doing a data cleaning in Power Query and after a long process I've managed to treat my data as I like but I'm stuck on the final step, which is a Merge Columns issue.

Basically I need to merge the "LabelsId.Label" Column with "Valor" Column only at the "null" fields. Is there a simple way of doing it?

 

Said another way, I need to Replace only the null values in "LabelsId.Label" by the "Valor" values.

 

Thanks
