Feature request - Poll grid log

Hi Pavel,

I'm with Vizimax Inc (manufacturer of IED in Canada) and appreciate very much your work. We use it a lot to test our devices (per 61850).
I would like to suggest a new feature to be added to future versions.

The objective would be to use the polling method to fill a log file with acquired data.
The principle would be like the Poll View but arranged as a grid (could be name Poll Grid)
First column would be date/time of the polling, then in each column we could drag a value from the data view
Note that even if each value is polled at a different absolute time, this would be irrelevant as interval would not be set to short values for this feature
Then, like the Poll View, a refresh interval could be set (but I would suggest a free form interval entry instead of a enum drop down... let say to set the interval to once per hour etc).
When started, this Poll Grid would start to fill out (one new line per refresh interval).
And the most important thing would be able to save the result into a .CSV log file.

Thanks and best regards,
