### What would you like to happen?
For certain data sources it would be useful to be able to repeat the value
of a field from the previous row.
It would be nice if we could add conditions for when to copy the previous
value:
* If the value of the field is null in the current row, take the value from
the previous row.
* If the value of the field is a specific value ('unknown') in the current
row, take the value from the previous row.
* If there **is** a specific value in another field ('A', 'B', 'C', ...),
take the value from the previous row
* If there **is not** a specific value in another field ('A', 'B', 'C',
...), take the value from the previous row
There are a number of use-cases linked to this:
* Data from spreadsheets and reports where field data from merged cells are
only available on the first row. We want to repeat from a previous row if a
field is null. This is similar to the "Repeat" option in Excel Input, Text
File Input, ...
* Data coming from multiple sources. If we have customer information from
multiple sources, the values for non-source data are null and needs repeating
from previous rows.
