When Trigger phrases in multiple topics are very similar

[DS2]

We are building a chatbot with a large number of topic (IS Service Desk based) and some of the topics are very close in nature (but different). 
For example, we might have these kind of topics that go along with printers:
1) Printer Maintenance

2) Printer Fix

3) Printer Ordering

Or, for email related requests:
1) Create a new email
2) Create a shared mailbox
3) Create a distributed group email

How can we best handle this with trigger phrases and if PVA runs across similar trigger phrases, is it possible for it to give the users an option?
It does not seem so. For the printer example, I have a trigger phrase for Printer Maintenance as "Printer Maintenance" and a trigger phrase in the other topic of Printer Fix as "Printer Fix" but when I type in Printer Fix the PVA chatbot brings back the topic of "Printer Maintenance," which is not desired. 
Anyone know how if you have very similar topics (but the process is entirely different underneath) that PVA can give an option of which topic to pick for the users?
