Not necessarily best practice, but it is something that bitbake has 
supported.

If you create a directory under myapplication_1.0 that is unique and not 
an override, you can specify the directory name
as the SRC_URI and bitbake will pull the directory and its contents in.

Something like 
meta-mylayer/recipes-management/myapplication/myapplication_1.0/mysources/<tons 
of source files>

and SRC_URI file://mysources

It should work.

Something like the following:

 > find recipes/
recipes/
recipes/myapp
recipes/myapp/files
recipes/myapp/files/mysources
recipes/myapp/files/mysources/Makefile
recipes/myapp/myapp_1.0.bb
 > cat recipes/myapp/myapp_1.0.bb
LICENSE="MIT"
LIC_FILES_CHKSUM = 
"file://${COREBASE}/meta/COPYING.MIT;md5=3da9cfbcb788c80a0384361b4de20420"

SRC_URI = "file://mysources"

S="${WORKDIR}/mysources"
