When using fill down on a column is it possible to increment row references rather than column references:
| --------------------- |
| =dogs!B15+cats!B27 |
| --------------------- |
| =dogs!C15+cats!C27 |
| --------------------- |
| =dogs!D15+cats!D27 |
| --------------------- |
etc.
rather than:
| --------------------- |
| =dogs!B15+cats!B27 |
| --------------------- |
| =dogs!B16+cats!B28 |
| --------------------- |
| =dogs!B17+cats!B29 |
| --------------------- |
etc.
