Map / to /index.ts?

With import maps, is it possible to map any import path ending with

to the same path +

index.ts

index.ts

index.ts

index.ts ?
Since import maps, unlike

compilerOptions.paths

compilerOptions.paths

compilerOptions.paths

compilerOptions.paths, don't accept

*

* placeholders, I guess not?

Map */ to */index.ts?
