  I'm afraid that that isn't supported right now, but I'll be adding support for it so it will be possible in the next version.

  
  

  You can do it in the "R" computed column btw with something like:

  Equipment %in% grep("Camera", Equipment, fixed=TRUE, value=TRUE)

  So the function in R that you're looking for is grepl(pattern, x) , which returns TRUE if an element of x contains the pattern (e.g., Camera). Unfortunately, this function is not in our whitelist so that won't work for now. In the meantime, you can use the following workaround:

  res <- rep(0, 100)
  res[grep("Camera", Equipment)] <- 1
  res
  

  here Equipment should contain the names that you want to match on. You could add fixed = true, but it should not matter for the result.

  
  

  Hope that helps!
