You mean if {appname} and {appname}-foo doesn't right?

the XDG icon spec has some kind of inheritance built into the name so

someaction.png

is chosen if you don't have

someaction-veryspecific.png

So you may want to use another way of prefixing that doesn't mess with that 
like and _ or just nothing at all.
