Random Trial Filler Dogs

I noticed that many people have been complaining that trials, especially higher ones like ODIE/TOTO have been running extremely slow, because no one enters or they can only put in one or two of their dogs that have a chance to win. My idea/solution for this is some automated filler dogs; perhaps once a trial reaches 3 dogs, it has 10-20 minutes to reach 5, and if it doesn't, then a random TP dog is subbed in {would be owned by Robyn} ranging from 500-6000, and the trial can run without owners being able to take advantage. The higher TP subs would make it possible for owners to still lose money, and although trials would run faster and growth accumulates faster, the fact that there is a chance that a sub dog can win can also lower the amount being thrown into the economy, especially considering the high prices in the Monthly Shop, among others, people would be more likely to spend if they could gain part of it back by trialing their dogs 6-7 times a day, rather than maybe 4.
