Crystal Reports Crosstab

Message

Can I have multiple entries in a crosstab or can I only have min or max.  I want a table like:

  Test 1

  Test 2

  Test 3

  Test 4

  Sample 1

  R

  R

  R

  R

  Sample 2

  R

  R

  R

  R

  R

  R

  Sample 3

  R

  R

  R

  R

  R

Where R is the result.  For some samples I may have mutiple results and need to display them all.  The only way I have managed it is to add additional rows.  This then looks untidy and gives empty cells.
