1-Can I add filtering for field_farm_area?
2-Can I directly load the fields in the excel or notepad file?
There are 1400 fields in field_farm_area. 50 fields in excel file.
instead of marking them one by one, can I make a batch transfer and select them?
You could explore customizing your instance to use the Entity Reference View Widget module (which we use for the field_farm_asset Asset reference field).
This requires creating a new View to be used for the widget (see the farm_asset_entityreference_view View as an example, which is used for asset references), and then changing the widget that is used for the field_farm_area in each of the Log types (under /admin/config/log/types).
Note that in farmOS 2.x, we will most likely be using the Entity Browser module for both the Asset reference field and the new Location reference field (because Areas are now types of Assets in 2.x).
