[Feature Request] Add default value on script custom parameters

[momolemo]

Hello,

The new script parameter function is pretty cool. Do you think you could add a parameter for a default value, that pre fill the input with the value. So if you often run the script with the same paramters you just clic next but when you sometime need to change it you could easily without change the code.

As a work around i set the field to optionnal and add in description but i think it is less obvisous for the user.

Regards
