Directions widget not updating travel modes when changing routing service

Question

I'm using Directions Widget available in Api for Javascript 3.39.

The user can choose two routing services. When I want to change the routing service, changing the RouteTask for the directings widget, it doesn't update the travel modes available to select from in the Travel Modes list.

How do I accomplish this?

Do I need to destroy the directions widget and create it again everytime the user changes the routing service? I need the user to be able to use the same input for both routing services, so if I need to destroy the object, I would need to save and recreate everything, and I would really like to avoid this, if possible.

They use different data, one over the data as it exist today, and another with data as it will exist in the future, and they want to be able to run the same scenario for both. I have thought about using two widgets, but the problem would remain the same as if I need to destroy the widget and recreate it, being that I need to clone the input from one to the other.

It's probably possible, but not recommended to mix 3x and 4x in the same project. I'd like to learn more about your use case though. Why do users need the option of choosing between two routing services? And why change them on-the-fly as opposed to making the choice up front? Have you tried having 2 Directions widgets?

I'll go cry in the corner now then, haha

I'm looking forward to the improvements in 4x for when we are able to migrate.
Is it possible for both apis to coexist within the same project? Maybe I could use the 4x Directions widget and leave the rest in 3x until we are able to migrate the whole project? Thank you!
