Wireguard Multiline Config Value

Is it possible to split a config command over multiple lines instead of one long string? E.g.

PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

When using more commands the line gets very long and unreadable. I would like to split it so that I can use one line per command. Something like:

PostUp = iptables -A FORWARD -i %i -j ACCEPT; \
   iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

The man page says it's based on the ini format but has no help on this topic.
