depending on your setup/requirements, you could use NFQUEUE and e.g.
python nfqueue bindings and scapy to add source routing ip options

-> use NFQUEUE target in OUTPUT or POSTROUTING chain to send packets of
your choosing to a queue
-> write a python program
-> use nfqueue bindings to receive packets from queue
(https://www.wzdftpd.net/blog/nfqueue-bindings.html)
-> use scapy (http://www.secdev.org/projects/scapy/) to add IP Options
and LSRR/SSRR and update the packet

have a look here for some examples:
