It is ABSOLUTELY possible to have both options. Kodi uses his litter box and goes outdoors. He MUCH prefers going outdoors, but that happened over time, at his own pace... We didn't force it.
We were committed to maintaining both options, so why would we try to reinforce one over the other? The fact is, that as he matured, we had to REALLY praise his litter box use, because he SO much preferred going outside.
I have to say, though, that going "near" the pee pad (or litter box) would not have been acceptable to me. Kodi missed occasionally as a puppy, and THAT we worked hard to correct. Of course, it meant watching him carefully, so that we could reposition him if needed, and it also meant making sure his litter box was bix enough that he could do his complete "potty dance" circle inside the box. But he learned. Oh, I should also mention that he has NEVER been willing to step on a previous wet spot in the litter during the "potty dance", which means that we have to keep the box VERY clean if we want him to poop there.
I think there are very few of us who give our Havanese both options that don't, eventually, find that they PREFER to use the outside, and we have to work to maintain the indoor option. ...but it's worth it! We just got back from a week of camping in the rain, and every time Kodi went outside to potty, it meant major clean-up. When it was REALLY bad, we just told him to use his box, especially in the early mornings, when he would want to get into bed and snuggle right after!!!
