javascript - Angular2 - assign pipe from a variable

Is it possible something like this:

{{property | some_variable_name}}

My goal is to use a pipe that is set in a JSON configuration (or a variable), but I'm not sure if it is possible to pass the pipe name in the interpolation this way.
Anybody tried something like this before?

The pipe needs to be listed in pipes: [MyPipeHere] in the @Component() decorator or in PLATFORM_PIPES, therefore this approach won't work.

What you can do instead is creating a custom pipe that calls other "pipes". A pipe is basically just a function, therefore this is easy.

You can pass a variable to your custom pipe like

{{property | my_custom_pipe:some_variable_name}}

this should be pretty close to what you want.
