Is it possible to define a single BUILD find with input parameters and have other folders/services in a mono repo use this BUILD file. Reason is that I have most of the same steps for most of the services and trying to avoid creating multiple BUILD files with just different parameters

There are macros/prelude files you can use, the contents of which will be available in all BUILD files. https://www.pantsbuild.org/docs/macros

Cool.. thanks again
