Pedal gradual release

I know this is a FAQ but I am still wondering if there is any way at this stage of development now to achieve a curved gradual pedal release as per the following snippet:

As my composer colleague points out, this is a fairly standard notation, and we are surprised there appears to be no means to achieve it. Any pointers gratefully received.

Alternative ideas to communicate a gradual release also welcome!

Irrespective of whether Dorico should or should not adopt this, one should not be surprised, given that curves are harder to manage (where to curve, how much to curve) than straight lines, that these were not among the first items added to the program.

Can you fake it with a slur?

Easy enough…

@Andro I set middle and end thickness to 1/8, so there’s no tapering.
