ios - watchkit image asset naming convention -

is there standard naming convention watchkit image assets when import them xcassets folder categorized correctly?

i've tried

    watchimage@2x~watch.png     watchimage@2x~38mm.png     watchimage~watch@2x.png     watchimage~38mm@2x.png 

none of worked.

currently, lot of work drag bunch of 38mm images media asset, set them device specific "apple watch" drag them correct slot, rinse , repeat 42mm images.

there isn't, unfortunately. apple support in future. ended writing automator script handle imports us.

i'd recommend filing enhancement radar on apple's bug reporting system.
