How can I import more then 25 items from external feed? / "L


Hello,
Thanks for a great product, but can you please let me know, how can I use "Link external data" to import more then 25 items from feed? For example when I import xml or ical feed from gCal I can see only first 25 records, the same with other feeds. Is it the same limitation as in google docs, when only 30 items can be imported?
Thank you.
