Is it possible for descriptionBlock to take a stored value as a number similar to what can be done in a Flexdashboard valueBox. For example,
column(
width = 4,
descriptionBlock(
text = "Attendance above 90%",
number = "`r on_track_breakdown_attendance`", #a way to accept a value that changes daily
numberColor = "success",
header = "Attendance",
rightBorder = TRUE,
marginBottom = FALSE
