Laravel Mix Split Image

i have 2 projects resource/js/www/ and resource/js/backoffice/ but problem is images like logo are compiled into same directory, how do i separate them?

mix.typeScript('resources/js/www/main.ts', 'js/www.js').vue().version()
mix.typeScript('resources/js/backoffice/main.ts', 'js/backoffice.js').vue().version()
