How can I edit train station (or combinators) settings in a blueprint?

[Calid]

Sometimes before capturing blueprint I might forget to set some settings, for instance, disable train limit, define some constants in combinator, etc.

It was not much of an issue in 1.x, as I would just fix the setup and recapture the blueprint.

But in 2.0, with parametrized blueprints, each time I fix the small mistake and create a new blueprint, I need to redefine all the parameters, variables, formulas, put them in the right order, too. Might get annoying sometimes.

I assume, the upgrade planner would be of no use here.

Is there an easy way to modify an existing blueprint?
