[PD] Is there something like "adddollar" for messages?

[Alexandros Drymonitis]

Like the title says...I'd like to generate the dollar sign in a message, in
a similar way you can use [addcomma( which will add a comma in a message.
Is there a way to do that?
For example, something like this:

[10(
|
[until]
|
[f ]x[+ 1]
|
[t f b]________
|                       [adddollar(
[add2 $1(       /
|                    /
|                   /
[                  (  <- this is an empty message

So in the empty message I can create the following:
$1
$2
$3
etc.

Of course this "adddollar" is fiction as it produces this error:
Bad arguments for message 'adddollar' to object 'message'
But is there a way to do this?
