Is it possible to advertise multiple locally-defined paths to the same destination with BGP addpath.

[tedelhourani]

I have this router topology

                        10.10.10.91
                               |
                               |
10.10.10.92 ----------    10.10.10.93 -------- 10.10.10.99

.93 is configured with addpath-tx-all-paths toward .99.
.93 is receiving paths to the same 192.168.100.0/24 destination from both .91 and .92
.93 advertises both paths to 192.168.100.0/24 to .99. This is all fine and working as expected, .99 received two paths to 192.168.100.0/24:

BGP table version is 48, local router ID is 10.10.10.99, vrf id 0
Default local pref 100, local AS 300
Status codes:  s suppressed, d damped, h history, * valid, > best, = multipath,
               i internal, r RIB-failure, S Stale, R Removed
Nexthop codes: @NNN nexthop's vrf id, < announce-nh-self
Origin codes:  i - IGP, e - EGP, ? - incomplete

   Network          Next Hop            Metric LocPrf Weight Path

Is there a way to statically configure AS paths/static routes to 192.168.100.0/24 on .93 such that it advertises these paths as if it had received them from .91 and .92? I removed the .92 an .91 neighbors from the config snippet below, because I think they are irrelevant to my question.

I tried configuring multiple static routes to "192.168.100.0/24", and "redistribute static" under "address-family ipv4 unicast". That didn't help as only one of the static routes was advertised.
