It is possible, although you may have to do a bit of coding to get that result. See Find Symbolic Variables in Expressions, Functions, Matrices for more information. It makes extensive use of the symvar function.

Note that logical operations on symbolic variables and expressions are not as straightforward as with numeric variables.
