Does BitBasis support efficient slicing?

[hz-xiaxz]

I hope to slice the LongBitStr like the intrinsic String type in Julia. For example, for Julia Strings it works like

julia> a = "abab"
"abab"

julia> a[1:2]
"ab"

where a[1:2] return the same String-typed result.

However for BitBasis 0.9.3 it returns a certain Vector type

julia> b = bit"0101"
0101 ₍₂₎

julia> b[1:2]
2-element Vector{Int64}:
 1
 0

julia> BitStr(b[1:2])
01 ₍₂₎

which needs an extra operation to convert it back to BitStr type, consuming computation time.
Is it possible to overload the slicing operation or provide a SubString function like discussed in StackOverflow?
