send periodic a list of messages without wrapping

Is it possible to send a list of messages periodically without wrapping when reaching the end of the list?
using the duration based on len(send_list) * cycle_time will overshoot and retransmit.

Creating a list of messages to send cyclic (including 20 or so muxed frames)

```
send_list = list()
for bmsg in bmsg_list:
send_list.append(can.Message(arbitration_id=txid, is_extended_id=False, data=bmsg._data))

duration = len(send_list) * inhibit
task = c.bus.send_periodic(send_list, inhibit, duration=duration)
```
