Add context for build system, not for keybinding

[hxss]

Is there a way to using build view only with specified build systems?
For example I want use it only with php. Will be comfortable set context for build system, not for keybinding.

{
	"cmd" : ["php", "$file"],
	"file_regex": "php$",
	"selector"  : "source.php",
	"context": [{"key": "build_fake", "operator":"equal", "operand":true}]
}

If I use onSaveBuild plugin - build view show correct output only by Ctrl+B, but on Ctrl+S I get a strange result(because there is no context).

If you bind bv to the build system - it will be able work with onSaveBuild and other key shortcuts(now on subl3 work only with Ctrl+b)

Cool. However, I don't know how to do this. I believe the way to do it is, I would need to customize Packages/Default/exec.py, based on this page http://docs.sublimetext.info/en/latest/reference/build_systems/basics.html#overriding-the-default-command-for-build-systems Any idea?
