Include resources from another folder (ALL languages at once)

Problem

I can place localised resource folder in my project (the resBase contains the default resource folder, namely resources) by adding them with following namings: resources-de, resources-en, ...

But I can not place them inside the second resource folder (the resBase also contains ../shared/resources) - if I try to place resources-de, resources-en and similar folders in my shared folder they are not used by my watchface.

Question

Can I somehow solve this more elgantly? Do I really need to define resources manually for all languages?

project.manifest = manifest.xml
srcBase=source;../shared/source;../shared/source2
resBase=resources;../shared/resources

// ...

# --------------------
# GROUP 280 - Fenix 6X
# --------------------

fenix6xpro.sourcePath = $(srcBase);../shared/source-fenix6x

# Test 1 - NOT WORKING
fenix6xpro.resourcePath = $(resBase)

# Test 2 - WORKING
fenix6xpro.resourcePath = $(resBase)
fenix6xpro.lang.ita = $(resBase.lang.ita);../shared/resources-ita
# define all languages one by one like that
