Is it possible to do something like this with a query plan?

I want to get
Query1

select * from tableA
where col1 like '%value%'

to run like

Query2

select * from tableA
where contains(col1, "value")

using a plan_guide.

Basically what's happening is a 3rd party product is executing a query that
looks like query1, which is searching on a text field (col1).

I wanted to try a full text index, but I don't think that I can get the
vendor to change their code to use a contains instead.

Any ideas?
