There is one way, but you need to ask the readers.
Example:
Let’s say your character’s name is LUCY and you want her new name to be something else, you can ask the reader:
NARR
What should Lucy’s new name be?
choice (LUCY)
“Anna”{
NARR
Her name is Anna now.
}“Maria”{
NARR
Her name is Maria now.
}“Type in your own”{
@pause for 0.7
input What is her name? | What is her name? | Done (LUCY)
NARR
Her name is [LUCY] now.
}
NARR
[LUCY] looks amazing!
*If you write [LUCY] in the script, it’ll show up as Anna for the people who chose Anna, Maria for the people who chose Maria and a random name that the reader gave to LUCY for the third option (so if I named her Lila, that would show up for me)
