Display TP and SL orders placed via FIX API in cTrader Desktop/Mobile apps as TP and SL on order

I can place orders via FIX API to act as SL and TP for an order, however these are displayed in the cTrader Desktop and Mobile apps as separate orders. I include the posMaintRptID when setting the SL and TP orders however this does not seem to be recognised in the cTrader Desktop/mobile apps. Each of the TP and SL orders are shown as a separate order instead of TP and SL on the existing order.

Steps I have followed using FIX API;

1) Place Sell Limit Order and receive ExecutionReport with posMaintRptID

8=FIX.4.4
9=219
35=8
34=2
49=CSERVER
50=TRADE
52=20200104-03:23:30.230
56=PEPPERSTONE.3327088
57=TRADE
11=ORD_1_TEST_STRATEGY
14=0
37=65668369
38=1
39=0
40=2
44=7605
54=2
55=10011
59=1
60=20200104-03:23:30.087
150=0
151=1
721=36539947
10=140

2) Place Buy Stop Order (SL) with the posMaintRptID received in the first step

8=FIX.4.4
9=188
35=D
34=6
49=PEPPERSTONE.3327088
50=TRADE
52=20200104-03:25:15.189
56=CSERVER
57=TRADE
11=ORD_1_TEST_STRATEGY_SL
38=1
40=3
54=1
55=10011
59=1
60=20200104-13:25:15.188
99=7610
721=36539947
10=175

3) Place Buy Limit Order (TP) with the posMaintRptID received in the first step

8=FIX.4.4
9=188
35=D
34=9
49=PEPPERSTONE.3327088
50=TRADE
52=20200104-03:26:36.443
56=CSERVER
57=TRADE
11=ORD_1_TEST_STRATEGY_TP
38=1
40=2
44=7600
54=1
55=10011
59=1
60=20200104-13:26:36.442
721=36539947
10=165

a) How can I set a SL and TP order via FIX API that is displayed in cTrader as the SL and TP on an existing order?

b) The ClOrdID set for an order placed through the FIX API is also not displayed in the cTrader Desktop/Mobile apps. How can the label field displayed in cTrader DeskTop/Mobile apps be set in FIX API?

Many Thanks
