Short arrows for incoming and outgoing messages lacks "from end to actor" option

Question

I noticed that I can use open and close square backet to change direction of incoming messages, but there is no equivalent for short incoming messages: AFAIK I cannot draw a short incoming message from the right of the screen to my last participant.

Is it possible to have this?

Hello E., and all,

But from right, short or long arrow are the same meaning and same length!...

Here are some examples:

@startuml
participant Alice as a
participant Bob   as b
b <-]      : ""<-] ""
b <-?      : ""<-? ""
@enduml

• Your request is to be able to differentiate the two arrows?

Regards,
Th.

In my rendering (done by vscode) they are not.

But I did not realize that I can invert the participants and the arrows as you did and use the question mark to get the short line.

Now my problem is solved.

Thanks.
