Can you adopt a 'specific' single property from another style? - less

Question

I'm pretty new to LESS and have been playing with ways to reuse properties from existing styles.
Is there a way I get reuse a Single Style/Property (by name) of a known CSS Class, for example:
This Obviously merges all of .source into .target:
.source { width: 100%; display: block; color: #ff0000; }
.target {
height: 10px;
.source;
}
What if I wanted just the width property, something like this:
.source { width: 100%; display: block; color: #ff0000; }
.target {
height: 10px;
width : .source:width;
}
I've been looking for a while now, and I'm doubtful its possible, but hoping someone has some suggestions.
Essentially I'm hoping to not generate tons of repeated CSS for properties I don't need.

Short Answer, Not at Present (as of version 1.7)
There is no way to target just a single property for retrieval without setting up the class to allow access to it. For example, if it was worth it to you, a class could be set up like so:
.source {
.get(#prop) when (#prop = width), (#prop = all) {width: 100%;}
.get(#prop) when (#prop = display), (#prop = all) {display: block;}
.get(#prop) when (#prop = color), (#prop = all) {color: #ff0000;}
.get(all);
}
.target {
height: 10px;
.source > .get(width);
}
This will get the output you want. But as you can see, it involves much more coding than just setting the properties on the two items themselves (or setting a global variable for both to access, which would be the better way to go). I cannot think of a situation when it would be best to use the above method, but maybe someone might find this useful.
