Is there an IBM group mark symbol?

I'm writing about the IBM 1401 and there's one character from its character
set that I couldn't find in Unicode: the group mark. The group mark is
three horizontal lines with a vertical line through it (see attached
image). This character is used in various books and publications, so it's a
"real" symbol that is used in text. Would it make sense for me to submit a
proposal to add this character?

Thank you,
