Nah. I think if I were you I’d have a formula field set up that would output text, and then I’d have a single automation that would paste the value of the formula field into the multiple select field
With reference to your examples above, I’d have:
IF(
{value} < 50,
"Low traffic,"
) &
IF(
FIND(
"Health Care",
{Cell}
),
"Animation,"
)
And so it’d output “Low Traffic, Animation,” if it met the criteria you’ve set above, and then the automation would paste it into the multiple select field
