I'm very new to cloudformation templates, and I'm trying to create a template to build AWS ECS codepipelines.
The pipelines will need a CodeBuild stage with a fairly complex buildspec.
I would like to be able specify the buildspec for the build project as a template parameter. However when creating the stack from the template, CloudFormation only seems to allow a single line text box for providing the value for the parameters.
Is there some way to tell it that a particular parameter is a "long text" string, to allow it to show a larger multi-line edit box?
